Problems solved by technology
[0003] 1) When the user finds that the server is down, it is obviously too late to go to the computer room to activate the backup server, resulting in a long downtime and constant complaints from users, and the IDC operator obviously has no better way to help users reply;
[0004] 2) For backup purposes, most users have to pay twice the cost to buy a server system, rent a cabinet for storage, and use expensive load balancing equipment to keep the two sets of server data synchronized. This solution is undoubtedly too expensive. unbearable;
[0005] 3) This solution is obviously not environmentally friendly, and consumes more energy

Embodiment
[0016] Such as figure 1 As shown, a virtual cloud host backup control device includes the Internet 1, a core switch 2, a virtual backup cloud host 3, a convergence access switch 4, and a user main server 5. Switch 4, user main server 5 is connected to aggregation access switch 4, the gateway of user main server 5 is configured on port2 / 1 of core switch 2, user main server 5 finally reaches Internet 1 through core switch 2, and provides web browsing for users Service, email service, background database query and other functions. The virtual backup cloud host 3 is connected to the core switch 2 through complex multi-links, and the ip address of the virtual backup cloud host 3 is synchronized with the main server 5 of the user.
[0017] Establish a complete automatic routing control mechanism in the core switch 2, which automatically scans the echo-icmp response packet of the ip of the user's main server 5 every 5 seconds. Once there is no response, the core switch 2 starts a ne...

The invention relates to a virtual cloud host backup control device which includes the Internet, a core switch, the virtual backup cloud host and a user main server. One end of the core switch connects with the Internet while the other end of the core switch connects with the virtual backup cloud host and the user main server; the core switch carries out a real-time and automatic scan of responses of the user main server; and if the user main server is down or has a physical fault, the core switch sends a signal to activate the virtual backup cloud host to provide an access to a user. Compared with the prior art, the virtual cloud host backup control device of the invention has advantages of saving cost, being capable of realizing zero downtime and the like.
Description
technical field [0001] The invention relates to a control device for a cloud computing system, in particular to a virtual cloud host backup control device. Background technique [0002] At present, the server of the enterprise is hosted in the IDC data center of the operator. Due to the large number of servers, when the server fails, a backup server needs to be activated. This solution has the following disadvantages: [0003] 1) When the user finds that the server is down, it is obviously too late to go to the computer room to activate the backup server, resulting in a long downtime and constant complaints from users, and the IDC operator obviously has no better way to help users reply; [0004] 2) For backup purposes, most users have to pay twice the cost to buy a server system, rent a cabinet for storage, and use expensive load balancing equipment to keep the two sets of server data synchronized. This solution is undoubtedly too expensive. unbearable; [0005] 3) This s...
